ABSTRACT:
The invention is an aircraft power generation system which includes a tandem generator (10) which includes left and right generators (14, 15) arranged within a single housing (12). The left and right generators (14, 15) are driven at the anti-drive end of the tandem generator (10) by a gear arrangement including gears (22), (24) and (26). A phase indexer (36) including a phase adjust nut (38) is arranged in conjunction with driven gear (26) to provide for "vernier" phase-alignment of the generator rotors. In an alternative embodiment, phase-alignment of the generator rotors is accomplished by arranging them in-line to form an in-line tandem generator (10').
In a preferred arrangement, an in-line generator (70) is arranged to be isolated from an aircraft engine via an electromechanical disconnect (108). The disconnect (108) includes a pin (130) activated by a solenoid (110), which upon receipt of a disconnect command or signal, pulls the pin (130) from a hole (131) in ring gear (114) thereby disconnecting the tandem generator (70).
